Mine is Year 13 at Kings Maths School:
What do they feel the quality of the experience is?
My DD loves it. Being such a small school the kids do get a great level of education at the individual level too. .
Is it more than going to the local sixth form?
Yes - of course the maths teaching is fab (they run math inset courses for teachers from outside). Teaching in other subjects is good but the maths teaching stands out.
Also, over the next few weeks instead of having full blown study leave, each student is given an individual timetable for revision sessions based on their individual needs/weaknesses. This seems to work very well for pulling in a few last minute marks in the exams
Or a private sixth form.
My DD had been in private schools previously. We chose Kings over the private system.
Are there a lot of extra opportunities?
In term 1 of year 12 they have language sessions choosing from Mandarin, Arabic, French and maybe a few others. They can then continue with that language by using the KCL Uni language lab. Sports are once a week with options such as the usual football and running and the not so usual rick climbing and badminton to name a few. School clubs have included Art club, Robotics club, magic club, dungeons and dragons club, knitting club. Students can set up a club if they can drum up interest.
Is it just very very hard Mathematics?
DD describes it as:
Set 1: Do seemingly impossible math
Sets2 and 3: Do some hard but cool maths
Set 4: Do enough to get A stars in both maths and FM
Is it a big range of students there in outlook and attitude united by a common love of maths or is everyone v studious and quiet from v similar backgrounds
Students come from all sorts of backgrounds - not all studious and quiet but many are likely quirky in their own way. There are regular cool kids and nerdy cool kids and everything in between but they all seem to get along.
This year they had 300+ applications for the 70 or so places so students there are going to love maths and/or be good at maths.
There was a recent OFSTED so once that report is published there'll be more information for prospective parents and students.
